TO-252-3L
SN79xxx
3 Terminal 1A Negative Voltage Regulator
Description
The SN79xxx series are three-terminal Negative regulators providing
over 1A output current with internal current limiting, thermal
shutdown and safe area protection. These regulators are useful in
a wide range of applications. Although they are just fixed voltage
regulators, the SN79xxx series can be used with external components to
obtain adjustable voltages and Currents.
Application
◈ Consumer and personal electronics
◈ SMPS post-regulator / dc-to-dc modules
◈ High-efficiency linear power supplies
